Low-cost solution-processed copper iodide replaces PEDOT:PSS in inverted planar heterojunction perovskite solar cells with high efficiency and enhanced stability.
Stability and scalability are essential urgent requirements for the commercialization of perovskite solar cells (PSCs), which retarded by non-ideal interface leading to non-radiative recombination degradation. Extensive efforts devoted reducing defects at surface. However, effects buried on degradation need be further investigated. Herein, an omnibearing strategy modify top surfaces film reduce interfacial defects, incorporating aluminum oxide (Al2 O3 ) as a dielectric layer growth scaffolds...
Low-temperature, solution-processed cerium oxide can serve as a promising electron transport layer to replace commonly used TiO<sub>2</sub> in planar perovskite solar cells, with high efficiency and enhanced stability.
Nickel oxide (NiO x ) has exhibited great potential as a hole transport layer (HTL) for fabricating efficient and stable perovskite solar cells (PSCs). However, it been greatly limited by its fabrication manipulation process. In this work, simple processing method on an ultrathin electrochemical mesoporous NiO film manipulated controllable ultraviolet/ozone (UVO) treatmentis employed; the duration of UVO treatment significantly affects photovoltaic properties PSCs. When exposure increases,...
A record power conversion efficiency of 20.1% is achieved for quasi-2D Ruddlesden–Popper perovskite solar cells. The quantum wells are reversely graded in the film, and confinement effect inside film significantly weakened.
Recently, lead (Pb) halide hybrid perovskites have emerged as sensitive X‐ray detectors due to their desirable charge transport properties and high absorption of ionizing photons. This work reports on a facile methodology for fabrication highly efficient PIN diodes based MAPbBr 3 (MA, methylammonium; Pb, lead; Br, bromide) single crystals detect energies ranging from 30 100 keV. The 2 mm thickness diode exhibits low dark current density 20 nA cm −2 at 150 V −1 sensitivity 23.6 μC mGy air ....
Tuning the polarity of green antisolvents (using various ethers) allows high control over purity intermediate phase triple-cation lead halide perovskite thin films.
Abstract Although incorporating multiple halogen (bromine) anions and alkali (rubidium) cations can improve the open‐circuit voltage ( V oc ) of perovskite solar cells (PSCs), severe loss poor stability have remained pivotal limitations to their further commercialization. In this study, acetylcholine (ACh + is anchored surface a quadruple‐cation provide additional electron states near valence band maximum surface, thereby enhancing alignment minimizing significantly. Moreover, quaternary...
Dual-mode photodetectors (PDs) have attracted increasing interest owing to their potential optoelectrical applications. However, the widespread use of PDs is still limited by high cost epitaxial semiconductors. In contrast, solution processability and wide spectral tunability perovskites led development various inexpensive high-performance optoelectronic devices. this study, we develop a electronically modulated dual-mode PD with near-infrared (NIR) narrowband visible light broadband...
Perovskite solar cells (PSCs) based on a NiO x hole transport layer (HTL) with an inverted p-i-n configuration have yielded highly efficient and relatively stable devices. Here, we develop simple electrochemical deposition method for quickly evenly preparing mesoporous film. It is demonstrated that the increasing thickness decreasing surface roughness of film are beneficial light transmission. The optimal condition films achieved by adjusting time at certain applied current density, which...
Abstract Previous reports of formamidinium/methylamine (FAMA)-mixed halide perovskite solar cells have focused mainly on controlling the morphology film and its interface—for example, through inclusion bromine surface passivation. In this paper, we describe a new processing pathway for growth high-quality bromine-free FAMAPbI 3 perovskites via control intermediate phase. Through low-temperature aging (LTAG) freshly deposited film, α-phase can be seeded in phase and, at same time, prevent...
Abstract The wide‐bandgap (WBG) perovskite solar cells (PSCs) and narrow‐bandgap organic (OSCs) integrated tandem (TSCs) show great potential for overwhelming single junction structure, especially the advantage of applying orthogonal solvents allowing solution processed each subcell. However, WBG with high Br content suffers from serious phase segregation voltage loss. commonly used interconnection layer (ICL) in TSCs requires a vacuum‐deposited thin metal recombination leading to remarkable...
